LO'COMOTIVE ENGINE AND TENDER COUPLING.

T 0 all whom. it may concern:

Be it known that I, PERCY M. HOLDS- woRTII. a citizen of the UnitedStates, residment in Locomotive Engine and Tender Couplers, of which thefollowing is a specification.

My invention relates to the coupling-bar of a locomotive engine andtender, which ordinarily consists of a horizontally arranged flat bar ofiron or steel coupled at its ends by pins inserted verticallytherethrough, and through jaws or brackets fixed to the engine andtender frames, whereby the latter, on driving the pins home, are drawntogether at their meeting ends, the said ends being usually providedwith chafing-irons or their equivalents, adapted to ride against eachother at all times.

My invention has for its object, to increase the coupling bearingsurface of the bar, to take up the wear of same, to dispense with theordinary ins and chafing-irons, and to enable the .coup ing-bar with itscombined arts to be readily disconnected for uncoup ing the engine'andtender.

Theinvention consists in features of novelty as hereinafter describedand claimed, reference being had to the accom' anying drawing formingpart of this speci cation, whereon,

Figure 1, 'is a vertical longitudinal section (partly in elevation)through my improved coupling-bar-and it's combined parts on line 1', 1,in Fig. 2; Fig. 2, a horizontal section (partly in top on line 2, 2, inig. 1; Fig. 3, a vertical transverse section through the coupling-bar online 3,' 3, in Fig. 1, looking to the right, showing its combinedpartsin end elevation, and Fig. 4, a similar view thereof looking to theleft.

Like letters and numerals of reference de note like-parts in allthefigures. (i represents my improved coupling bar which is composedpreferably of; cast steel mtegral throughout and having'its shank 'orbody 1 preferably tubular in cross section.
